ATTACHMENT FOR LOOMS.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed April 18, 1914. Serial No. 832,840.

To all whom it may concern Be it known that I, ERNEST HALL, a citizen of the United States, and a resident of Kannapolis, in the county of Cabarrus and Stateof North Carolina, have invented a new and useful Improvement in Attachments for Looms, of which the following is a specification.

My invention is an improvement in attachments for looms of any character, but especially for the Crompton-Knowles terry loom, and has for its object to provide an attachment of the character specified, which may be applied to or detached from a loom of any character, and wherein mechanism is provided for connecting a rotating part of the loom with the pile rollers for operating the said rollers during the weaving of terry or pile material, to deliver an even and uniform pile of any desired length, the said connection being operated to connect and disconnect the rotating part of the loom with the pile rollers by the pattern chain.

In the drawings :Figure 1 is a front view of a portion of a loom provided with the attachment, Fig. 2 is an end view of Fig. 1, Fig. 3 is a top plan view of the attachment with parts in section, and Fig. 4 is a perspective view of the clutch operating mechanism.

The Crompton-Knowles terry loom is, as is known, capable of weaving pile cloth or plain cloth, as may be desired. The attachment is designed to be connected with the loom, and is driven thereby.

A gear wheel 1 is arranged on a stub shaft 2, which extends horizontally from a sup porting bracket 3, which is bolted to the frame of a loom and is designed to support the entire attachment. The gear wheel 2 is driven by the loom, and a bevel gear wheel 4 is secured to the gear wheel at the outer side thereof.

The bevel gear 4 meshes with a bevel gear 5, which is secured to the lower end of a shaft 6, journaled in bearings 7 and 7 supported by the bracket 3, before mentioned. The upper end of the shaft 6 is provided with a worm 8, which meshes with a worm wheel 9, secured to a sleeve 10, which is journaled on a shaft 11, supported by the bracket 3, before mentioned.

One of the sections 12 of a clutch is feathered on the sleeve 10 and the other section 12 of the clutch is secured to a sleeve 13, also journaled on. the shaft 11., The sleeve 13 is provided with a wide pinion 14, which meshes with a pinion 15 on the pile roller 17. The pile rollers are arranged as shown in Fig. 1, and the gear wheel 15 of the roller 17 meshes with a gear wheel 16 on the roller 18, in such manner that the pinion 14; when in operation will drive the rollers 17 and 18.

The clutch section 12 is provided with a hub, having an annular groove 20, which is engaged by the arms of a fork on the lower end of a lever 21. The lever 21 is connected to the mechanism which is operated by the pattern chain of the loom, to move the said clutch section toward and from the section 12 The clutch sections 12 and 12 are connected at all times when weaving pile material. "When weaving plain cloth, the sections are disengaged. A bracket comprising a body 23 and arms 22 and 22 extending approximately parallel and in the same direction from the body is mounted in a manner to be described, and its movement is controlled by the pattern chain.

Each arm 22 and 22 is pivoted to a vertical brace or strut 24, which extends up wardly from the bracket 3, in such manner that when the free end of the arm 22 is lifted, the arm 22 will be swung in the same direction.

The lever 21 is connected to the arm 22 in such manner that when the bracket arm is operated by the pattern chain, the clutch section 12 will be moved toward or from the section 12 to connect or disconnect the sleeve 10 and the sleeve 13.

When the clutch sections 12 and 12- are connected, the gear wheel 14: will be driven from the worm 8, and the worm 8 is so related to the worm wheel 9, that one complete rotation of the worm 8 will move the worm wheel 9 a distance of one tooth. That is, the sleeve 10 is rotated a distance of one tooth of the wheel 9 from every complete rotation of the shaft 6, and the connection between the worm 8 and the rotating part of the loom which drives the gear wheel 1 is such that the worm 8 will make a complete rotation every three picks of the loom.

The length of the pile delivered by the pile rollers 17 and 18 is in accordance with the number of teeth on the gear wheel 14:, and the length may be varied by varying the number of teeth of the said wheel, the number of teeth being increased to increase the length of the pile delivered and decreased to have the pile shorter. The gear 14: is intended to be interchangeable, in ordelr to provide for any desired length of pi e.

It will be understood that the pile rollers 17 and 18 are the pile feeding rollers, which withdraw the pile from the warp beam and deliver it to the cloth being woven. The said rollers in practice are mounted in bearings which are adjustable toward and from the shaft 11, and the interchangeable gears 14 are of the same ,pitch, regardless of size. When the smaller gear 14: is used, the pile feeding rollers are adjusted toward the shaft 11, while when a larger gear 14 is used, .the said rollers are adjusted away from the shaft 11.

Mechanism indicated at 25 and operated by the pattern chain connects the clutch 12-l2 when it is desired to weave terry or pile material, while when it is desired to weave plain material the clutch sections are disengaged.

The outer end of the portion 22 of the bracket 22-22-23 is moved upward by a riser on the pattern chain. A lever, not shown, rests upon the pattern chain, and the rod head 25 shown in Figs. 1 and 2 is con nected to the lever. WVhen the riser on the pattern chain engages the lever, it will swing the bracket 222223 in a direction to release the clutch section, and the sections are engaged and disengaged in accordance with the indications from the pattern chain.

It will be understood that the improved attachment is designed for attachment to any make of loom being shown in the present instance with the Crompton-Knowles, and the attachment provides for a positive uniform feeding of a certain amount of pile warp at every three picks of the loom. The sleeve 10 is held on the shaft 11 by means of a collar 26, and a set screw 27 which is threaded through the collar into engagement with the shaft.

The operation of the attachment is as follows: It will be understood that in weaving terry cloth the clutch sections 12 and 12 are connected throughout the weave, and they are disconnected only when it is desired to weave a strip of plain cloth, as for instance to provide ornamentation at the end of the towel. Whenever the clutch sections 12 and 12 are connected as above mentioned, the pile warp is fed by the feeding rollers 17 and 18 every three picks of the loom. The pattern chain is so arranged that it does not operate the bracket 2222 23 during the weaving of the terry cloth; The gear wheel 1 is rotated continuously from the moving part of the loom, and the shaft 6 is also rotated continuously. The bevel gear wheels 4: and 5 are so related that for each three rotations of the bevel gear 4 the bevel gear 5 will be rotated once. Thus the shaft 6 and the worm 8 are rotated a complete rotation for every three complete rotations of the gear wheel 1. When the clutch sections 12 and 12Tare connected, the worm wheel 9 and the gear wheel 14 will be moved a distance of one tooth of the worm wheel 9, for each complete rotation of the shaft 6 and the worm 8, and since the shaft 6 and the worm 8 rotate once for each three picks of the loom, the pile rollers 17 and 18 will deliver warp at every three picks of the loom. The gear wheels 17 and 18 are never changed, the said wheels being moved toward or from the shaft 11 in accordance with the size of gear 14 used.
